“Elysium” cost $115 million to produce and will roll out in more than 2,700 theaters.

It faces fierce competition from the raunchy comedy "We're the Millers" and the family adventure "Percy Jackson: Sea of Monsters,” both of which got a head start on the competition by opening on Wednesday.

"We're the Millers" netted $4.7 million on Thursday and has made more than $11 million over its first two days of release. "Percy Jackson" grossed $3.4 million on Thursday and has made nearly $9 million. Both movies could earn between $25 million to $30 million over their first five days of release.
